Title: Separate excitation system generator
Inventor: OOKAWA KOUKICHI
IPC: H02K1/02
Filed: 1978-11-15
Abstract: PURPOSE: To obtain high voltage, by utilizing the rectangular hysteresis characteristics of half-hard magnetic materials by using the half-hard magnetic materials as one portion of a magnetic circuit of the separate excitation system generator.  
     CONSTITUTION: A stator core 1 is formed in such a manner that armature cores 2a, 2b to which armature coils 5a, 5b are wound and field cores 3a, 3b to which field coils 6a, 6b are wound are arranged at locations, which mutually part at the angles of 90°, while fan-shaped yoke portions 4a∼4d are disposed at the four corners, and an inductor 9 is mounted to a shaft 8. At least one portion of a magnetic circuit consisting of the stator core 1 and the inductor 9 such as the armature core 2a, 2b portions is made up by half-hard magnetic materials with rectangular hysteresis characteristics. When the inductor 9 is revolved by DC-exciting the field coils 6a, 6b, magnetig flux flow through the armature cores 2a, 2b alternates, but a coefficient of variation in time of the magnetic flux becomes extremely large owing to the rectangular hysteresis characteristics of the armature cores 2a, 2b, and high voltage is generated at the armature coils 5a, 5b.

Abstract: PURPOSE:To drastically decrease the crosstalk in a wavelength selective filter chip without increasing an insertion loss by forming the filter chip of a transparent sheet formed of thin wavelength selective films in two sheets. CONSTITUTION:A slit 4 is formed at the prescribed point, i.e., branch point A' of an optical fiber 11 and the wavelength selective filter chip 15 is inserted and disposed in this slit 14. The wavelength selective filter chip 5 consists of the thin wavelength selective films 15b, 15c deposited by evaporation on both faces of the transparent sheet 15a consisting of glass, etc. An optical fiber 12 is so disposed that the optical axis of the incident light signal on the optical fiber 11 aligns to the optical axis of the optical fiber when said signal is reflected by the thin wavelength selective film 15b of the wavelength selective filter chip 15. The light signal entered by the one layer 15b is reflected to the branch path in such a manner and the light signal is reflected when the light signal which is ought to be intrinsically reflected by the first thin film is transmitted through the thin film 15b by the other one layer 15c, by which the crosstalk is prevented.

Title: Power ic
Inventor: SEKI YASUJI
IPC: H02H7/12
Filed: 1989-06-02
Abstract: PURPOSE:To turn off and protect from overcurrent all the semiconductor devices in upper and lower arms by inputting an overcurrent detection signal into a control signal interruption circuit through a photocoupler. CONSTITUTION:Usually, a control signal outputted from a control circuit is insulated by a photocoupler 6a through a signal interruption circuit 8, sent to drive circuits 4a to 4d for upper and lower arms and performs switching of transistors 2a to 2f. When the main circuit of a power IC 10 gets in an overcurrent state, an overcurrent detection circuit 7 delivers output. This output is insulated by a photocoupler 6b and sent to the control signal interruption circuit 8, where the control signal from a control circuit 5 is interrupted. Consequently, no control signal will be sent after the photocoupler 6a. On that account, the transistors 2a to 2f for the upper and lower arms are all turned off.

IPC: G11B7/0045
Filed: 1994-05-31
Abstract: PURPOSE:To form visible patterns in prescribed places merely by execution of one time of delay quantity adjustment by providing the above recorder with a delay circuit capable of varying the delay quantity within a data unit where scrambling treatment at the time of EFM modulation is executed. CONSTITUTION:Such original data (excluding synchronizing patterns) that marking pits, for example, 11T patterns, are formable only at the data of the first byte of respective frames after obtaining an EFM signal is formed and is sent to an EFM encoder 5. The output thereof is checked. At this time, the timing for blocking is shifted by one step each at every specified period. If the appearance of the marking bit, for example, 11T pattern, in the prescribed position of the EFM-modulated signal is checked, the timing thereof is regarded to be the adequate delay quantity. Henceforce, the blocking is executed at this timing. The data arrangement as expected on the medium is then formed when the original data for visible patterns is inputted.

Abstract: PURPOSE:To reduce the load of an automobile internal combustion engine equipped with a fuel injection pump and the air conditioner, by stopping a compressor for the air conditioner when the fuel temperature has exceeded a set temperature. CONSTITUTION:When the detected value of a fuel temperature detector 5 or a temperature detector 9 has exceeded, a thermoswitch 4 is turned off. Therefore, an electric current from a battery 1 through an air conditioner controlling circuit 2 to a magnetic clutch 3 is cut off and the compressor for the air conditioner is stopped.
